Energy and Exergy Measurement for Papermaking Processes

Abstract

This paper presents a three-phase energy model for the measurement and analysis of energy system in papermaking processes. A new classification and implementation procedure is made for the three-phase modelling. To demonstrate the effectiveness of the proposed modelling technique, a paper mill has been taken as an example where the energy and exergy efficiencies have been obtained and the potential production units for energy saving have been identified and the improvement on the efficiency of energy usage in the mill is presented. The result shows that the proposed three-phase model can provide a quantitative analysis tool for the assessment of the energy system in papermaking.
